Public bug reported:

Binary package hint: xserver-xorg-video-ati

When I click on Guest session three things can happen:

1. The Guest session is started and everything works correctly. This
happened only when I tried booting ubuntu with very few Startup
Applications enabled and I started the Guest session without other
applications running.

2. This is the most common situation. The Guest session is started and works correctly, but the screen on VT8 only shows frozen garbage (i.e. corrupted fragments of what was present on the screen in VT7, see attached images 01 and 02). I can't see anything in the Guest session but everything works: I can switch back to VT7 and I can even close the Guest session using blindly my mouse and keyboard.
I noticed that when I press CTRL-ALT-F7, after leaving the corrupted VT8 screen and just before entering VT7, I can see for a moment an image of the Guest session screen updated and without any corruption.
Usually the mouse pointer never gets corrupted and behaves correctly, but sometimes instead of the mouse pointer I see a square of garbage. Sometimes the system suddenly hangs of reboots.

3. It seems that the Guest session is starting, but the screen becomes
black and a mesmerizing waterfall of light slowly starts drawing some
scary grey clouds on the screen (see attached image 03). The system
completely hangs and the sysrq keys don't have any effect.
